Fast food chains like Mickey D'sand Burger King have already removed the options from kids meals, though soda ads are still plastered all over their menus, so it's not really out-of-sight, out-of-mind.

Nearly a third of U.S. adults, around 78 million, are obese, and 17 percent of children 2-18 years old are considered obese; that's 12.7 million kids.

A study in the journal Obesity found when healthier menu options were available to children, orders of fries and soda decreased and orders of healthier options, like strawberries and milk, increased –– even though the meal was pricier.
